Thermostat Heat Anticipator - IBC VFC 15-150 Installation And Operating Instructions Manual

VFC 15-150, VFC 45-225 MODULATING GAS BOILERS

1.8.6 Thermostat Heat Anticipator

IBC "Therm." contacts draw no power, so an anticipator setting for the thermostat
is not applicable with the VFC modulating series boilers. In the case of a single
temperature / heat load where zone valves are used to manage individual
thermostatically controlled zones, each room thermostat's heat anticipator should
be adjusted to the current draw of its associated zone valve.
